To improve bot detection and prevent them from creating sessions, you can enhance your isBot method by using a more comprehensive list of known bot user agents. Additionally, consider using third-party libraries or services that specialize in bot detection. Here's an improved approach:
-
Enhance the Bot Detection Regex: Expand the regex pattern to include more known bot user agents.
-
Use a Third-Party Library: Consider using a library like
jaybizzle/crawler-detectwhich is specifically designed to detect crawlers and bots.
Here's how you can implement these improvements:
Enhanced Regex Pattern
You can expand the regex pattern to include more known bot identifiers. However, this approach can become cumbersome and may still miss some bots.
